The following is a description of the sequence for one complete. firing cycle beginning after a cartridge is chambered Knowing. the correct function of your rifle will help you with the diagnosis. of any malfunctions or failures to fire, The trigger is pulled releasing the hammer which strikes the. firing pin The firing pin impacts the primer in the chambered. cartridge igniting the primer which ignites the powder As the. powder is burned it creates a high volume of gas which propels. the bullet down the bore of the barrel The exhaust gas is also. vented out of the bore through the barrel s gas port into the. front sight base and through the gas tube and into the carrier. key on the bolt carrier The gas pushes the bolt carrier back. unlocking your bolt from the barrel extension allowing the bolt. carrier to recoil completely The underside of the bolt will push. the hammer down where it is caught and held by the. disconnector The bolt will pull the spent cartridge out of the. chamber and eject it from the rifle, At full recoil the carrier has pushed the buffer and buffer spring. back into the receiver extension The magazine will present a. new cartridge which will be stripped from the magazine by the. bolt as the recoil spring pushes the bolt carrier group back into. battery The new cartridge is now chambered The fire control. group will reset once you have released the trigger allowing the. disconnector to release the hammer and re engage the trigger s. sear The rifle is ready to be fired again or put on SAFE and. 6 Align your sights on your target, 7 Place the selector on FIRE Your rifle is now ready to. 8 Squeeze the trigger until the hammer is released. Zeroing Your Sights,U S Marine Corps,25 Meter Zeroing Procedure. By following the steps below and establishing a zero at 25 meters. using a 25 meter sight in target your rifle sights will be set with a 300. meter battlesight,Do not move front sight post at,this time it was set at the factory. and should be very close to your,zero The rear sight aperture. should also be centered from the,factory with the unmarked large. aperture up If the aperture is,not centered turn the windage. knob clockwise to adjust the,aperture to the right or counter. clockwise to adjust the aperture,to the left until centered this is. called mechanical zero, 1 Rotate elevation knob in the down direction counter. clockwise The elevation knob should stop three clicks past. the 300 meter mark The rear sight should be all the way down. on the last whole click before it bottoms out This is called. mechanical zero elevation for the rear sight If your range. scale will not line up in the above manner an armorer will be. required to adjust the range scale for you, 2 Rotate the elevation knob up one click past the 300 meter. mark From this point on the rear sight elevation knob should. not be moved Any changes in elevation required in the. following zeroing steps are made to the front sight post only. 3 Carefully aim and fire at the center of the,target bull s eye Take your time and be. sure to use the sight picture illustrated,Zeroing Your Sights. 4 If your shot group is not in the center of the bulls eye use the. squares on the target sheet to calculate the required clicks. necessary to move your next shot group into the bulls eye. Changes in elevation are made by moving the front sight post The. squares are numbered around the edges of the target to equal the. number of clicks required to move the shot group to the bull s eye In. order to raise your next shot group rotate the front sight post. clockwise One click will move the strike of the bullet one vertical. square on the target sheet In order to lower your next shot group. rotate the front sight post counter clockwise One click as above. equals one square, Changes in windage are made with the windage knob Three clicks. will move the strike of the bullet one horizontal square on the target. sheet In order to move the shot group to the left turn the windage. knob counter clockwise In order to move the shot group to the right. turn the windage knob clockwise, 5 Carefully aim and fire another group at the center of the target. bulls eye Repeat steps 3 through 5 if required, If your group is on target your sight is now calibrated To place your. actual 300 meter zero on the rifle you must rotate the elevation knob. one click down The range scale s 300 meter mark should now be. aligned with the mark on the receiver, This manual was printed from a PDF and was not included with. an original CMMG Rifle If you have any doubts as to the. authenticity of the any rifle that came with this manual please. contact us,Disassembly Instructions, Before disassembling your rifle please unload and clear your. rifle as described in the unloading directions, 1 Reverify your rifle is unloaded and return the bolt and. carrier in to battery,2 If you need to remove the handguards it is. easier to do so while the upper is joined to,the lower The handguards can remain in. place for all end user maintenance Place,the butt of the rifle on a solid surface Pull. down on the Delta ring with even tension,on each side at the same time pulling one. section of the two piece handguard away,from the other Set the first half aside and. repeat the process for the remaining half, 3 Partially push the rear take down pin and the front pivot. pin from left so they are not captured by the detents that. retain them in the receiver in the closed position Use a.
